Hi Alex, here's some piece of the code: // vector layer layerHover = new OpenLayers.Layer.Vector("Hover");
// wms/wfs layer layerWMS = new OpenLayers.Layer.WMS( "regions WMS", " http://spssoww5d.sso.msp.gouv.qc.ca/cgi-wms/mapserv.exe?map=E:/ms4w/msp/wfs/botinSI.map& ", {layers: 'BDGA_REGIO_S_POLY_1M', format: 'image/gif', transparent: true, visibility: true } ); //control to launch wfs call on hover control = new OpenLayers.Control.GetFeature({ protocol: OpenLayers.Protocol.WFS.fromWMSLayer(layerWMS), hover: true }); //never called, see explanation below control.events.register("hoverfeature", this, function(e) { layerHover.addFeatures([e.feature]); }); As I said, The WFS call is maded on hover and I can see the GML in the response. In the request function of the GetFeature.js file: result.features = void BUT result.priv.responseText contain the GML response so when this function is called, nothing happens since result.features is null/void request: function(bounds, options) { options = options || {}; var filter = new OpenLayers.Filter.Spatial({ type: OpenLayers.Filter.Spatial.BBOX, value: bounds }); var response = this.protocol.read({ maxFeatures: options.single == true ? this.maxFeatures : undefined, filter: filter, callback: function(result) { if(result.code == 1) { if(result.features.length) { if(options.single == true) { this.selectBestFeature(result.features, bounds.getCenterLonLat(), options); } else { this.select(result.features); } } else if(options.hover) { this.hoverSelect(); } else { this.events.triggerEvent("clickout"); if(this.clickout) { this.unselectAll(); } } // Reset the cursor. OpenLayers.Element.removeClass(this.map.div, "olCursorWait"); }, scope: this }); if(options.hover == true) { this.hoverRequest = response.priv; } }, 2009/5/29 Alexandre Dube <ad...@mapgears.com> > Hi Martin, > > It could be a namespace issue.
